California Air Resources Board

Building upon CARB's prior Vision scenario planning projects in 2009 and 2012, the agency formed a permanent scenario planning program. Scenario planning helps CARB evaluate hypothetical vehicle and fuel sector changes beyond current program time frames to gain insights on what is necessary to achieve long-term emission goals. To best inform upcoming policy decisions, the new program has developed an expanded and improved scenario planning tool, called CARB Vision 2.1. Initial scenarios have been created to launch public discussion on long-term actions. The new tool and baseline scenario assumptions build on the most recent policy developments and emissions projections for future years.
